7 Claims.

My invention relates, more particularly, to ventilators provided for useon the roofs of barns, stables and the like, and which are relativelylarge bulky structures formed principally of sheet metal.

As structures of this general character have hitherto been provided thematter of cost of transportation thereof has been an important factor inthe cost of the ventilators to the purchaser},

in spite of the fact that prior structures have been provided inseparable sections adapting them to be shipped in knocked-down conditionwhich, while reducing the cost of transportation as compared with thecost were they to be shipped in set up condition, has not permitted ofthe condensing of the parts, in knocked-down condition, into asufiiciently compact assembly to render transportation charges a minorpart of the cost to the purchaser.

One of my objects is to provide a ventilator of such construction thatwhen in knocked-down condition with its parts packed into a crate forshipping purposes, it will occupy much less space than ventilators ashitherto provided and similarly conditioned, thereby permitting, in thecase of transportation by rail, the storing in a car of many times thenumber of era-ted ventilators possible to be stored therein whenconstructed as has been the general practice hitherto.

Another object is to provide a novel and simple construction ofventilator the parts of which may be readily and quickly assembled inthe setting up of the ventilator, and which will be durable and rigid.

Another object is to provide a construction of ventilator the parts ofwhich may be assembled by one person only, at the point of applicationto the building to be equipped therewith; and otherobjects as will bemanifest from the following description.

Referring to the accompanying drawings:

Figures 10 and 11 are enlarged, broken, vertical sectional views takenthrough the upper edge of the lower section of the base-portion of theventilator at different portions thereof; and

Figure 12, a plan view of one of the plurality of similar bracketsforming parts of the ventilator.

The construction shown comprises a hollow pipe-like body portion open atits upper and lower ends and formed of superposed sections 12, 13, 15and 14, the lowermost section 12 which, as also the section 13, is ofrectangular shape in cross section, being so shaped at its lower edge inaccordance with common practice, that it is adapted to straddle and seatupon, the V-shaped roof of a barn, or other structure to be equippedwith the ventilators, at the vent opening in the roof.

The section 14 is provided with an outwardly flaring ring-shaped portion15 forming a stormliange periorated at its lower edge as represented at15 to permit rain flowing into the space between it and the portion ofthe section 14 which it surrounds to drain therefrom, the flange 15being riveted to the section 14, as indicated at 16, and its upper edgeportion outwardly turned to form a rim, or flange, 1'? containingopenings to receive bolts hereinafter referred to.

Located above the section 14 and vertically spaced therefrom, is a roof-portion 18 in the form of a hollow cone on which, in accordance withcommon practice, is mounted a bracket cone 19 rigid therewith and shownas supporting a weather vane 20 and an ornament 21, the lower edge ofthe roof-portion 18 having a continuous outwardly extending flange 18 ofapproximately the same diameter as the flange portion 1'7.

Surrounding the space between the body section 14 and the roof-portion18 is a storm-band 22 to which substantially V-shaped brackets 23disposed in a circular series about the inner side of the band 22 arerigidly secured, as by the rivets 24, these rivets extending through theapex portions of these brackets, the inner edges of the legs of whichare formed, preferably by bending the metal of which the legs are made,into ver- 11o tically disposed tube-portions 23 slotted as indicated at25.

The legs of the brackets 23 extend into the space between the bodysection 14, at the storm-flange 15, and the roof-portion 18, these legssetting on the flange 17. The roof-portion 18, in turn, is supported atits flange 18 on the legs of the brackets 23. Pins, in the form of bolts26, extend through openings in the flange 18*, the tube-portions of thelegs of the brackets 23 and the openings in the flange 17 and rigidlyclamp these parts together.

An annular mesh-member or screen, preferably of wire, and represented at27 fits in the space between the body section 14, at the storm-flange15, and the roof portion 18 for the usual purpose, and is held in placeby ties 28 secured to the member 2'7 and looped about the bolts 26 atthe slots in the legs of the brackets 23.

Referring to the detailed construction of the body-sections 12 and 13and the means for connecting them together, the section 12 is providedabout its upper edge with a cornice 29 extending continuously thereaboutand having an inwardly bent flange 30 terminating in a dependingextension 31, whereby the cornice presents a continuous downwardlyopening channel 32 at which the cornice extends over the upper edge ofthe bodysection 12. At each of the upper corners of the body-section 12is a bracket plate 33 (Figs. 5, 7 and 9) formed of a plate portion 34and upwardly extending flanges 35 which extend upwardly into the channel32.

The body-section 12 is provided with straps 36 one at each corner of thesection 12 at the inside thereof, these straps extending at their upperends into the channels 32 between the adjacent flanges 35 and the upperedge of the body-section 12 as shown (Fig. 7).

The bracket-plates 33, body-section 12, cornice 29 and straps 36 arepermanently secured together by rivets 37 and 3'7 the rivets 37extending through the extension 31, flanges 35 of the brackets 33, thebody-section 12 and the upper edge of the cornice 29, and the rivets 3'7extending through the parts just mentioned and in addition through theupper ends of the straps 36 (Fig. 11). The metal of the upper edges ofthe cornice 29, body section 12, flanges 35 and extension 31 is intendedas represented at 37 (Figs. 9 and 10) The body section 13 at its fourcorners is provided with plate-brackets 38 each formed of a plateportion 39 and depending flanges 4.0 which extend at their flanges 40into an upwardly opening channel 41 extending continuously around thelower edge of the body-section 13 and preferably formed by bending upthe metal at the lower edge of the body section 13 as represented at 42.

The brackets 38 and the body-section 13 are rigidly secured together byrivets 43 extending through the flanges ii), the lower edge of the bodysection 13 and the flanges 42, and by indenting these parts as explainedin connection with the body section 12.

The body-sections 12 and 13 are connected together,in the set-upcondition of the ventilator, by means of bolts 44 which pass throughopenings 35 and 46 in the brackets 33 and 38 at each corner of the bodystructure, as shown at one corner of Figs. 5 and 7, filler-blocks 38being preferably interposed betwen the'se brackets 33 and 38 forresisting deflection of the plate portions 34 and 39 thereof andpreventing the springing of the flange extension 31.

The straps 36 are provided for attachment, at their lower ends, to anysuitable part of the roof of the building to be equipped with theventilator, as for example by extending downwardly through the openingin the roof and attached to girders of the building to aid in preventingdisplacement of the ventilator; these straps also serving as means forholding the bodysection 12 against displacement in'the crate in whichthe ventilator in knocked-down condition would be shipped, ashereinafter described.

The assembling of the parts of the ventilator for shipping purposes isrepresented in Figs. 1, 2 and 3 wherein a crate, constituting one of theforms of which may be used, is shown at 47. In assembling the parts inthe crate 17 the roofportion 18 with the parts carried thereby is placedcentrally on the bottom of the crate and secured thereto by screws 48(one only of which is shown) extending through openings in the flange 18and into the two crosswise extending boards 49 and 50 forming the bottomof the crate. The structure formed of the two permanently unitedbodysections 13 and 14 is then positioned in the crate in surroundingrelationship to the roof-portion 18 to rest on the bottom of the crate,in which position it is secured by bolts 51 extending through theopenings 16 in the bracket-plates 39 and through openings in the boards49 and 50, the flller blocks 38 being preferably interposed between thebracket plates 39 and the boards. The body-section 12 is then introducedinto the crate to extend in encircling position about the structureformed of the body-sections 13 and 14 to rest at its lower edge on thebottom of the crate, the lower ends of the straps 36 being bent upwardlyaround the lower side boards 52 of the crate and secured thereto as bythe nails represented at 53. The storm band 22 is then placed in thecrate to surround the upper end of the body-section 14 with thetube-portions 23 of the brackets 23 positioned directly beneath theflanges 17, and the band 22 and body-section 14 rigidly secured togetherby the bolts 26 which extend through the tube portions 23 and the flange1'7, the band 22 thus being supported by this flange.

As will be noted from the foregoing, the relative proportioning of theseveral parts of the Ventilator as shown permits them to be nested intohighly compact knocked-down condition for shipping and to present acrated assembly of such dimensions that the number of such unitassemblies that may be stored in a box car of the usual dimensions, willexceed many times the number of ventilators which may be stored thereinwhen crated, in accordance with common practice, it being noted that theheight of the structure formed of the permanently connected bodysections 13 and 14 is substantially the same as the combined height ofthe body portion 12 and storm flange 22; and that the combined height ofthe roof portion 18 and the ornament commonly provided on such structureis also substantially equal to the combined height of the body section12 and storm flange 22.

Furthermore, as a matter of economy in packing and security againstdamage to the ventilator in shipping, the body section 12 at its loweredge portion is of substantially the same size as the cornice 29,measuring the latter about its peripheral portion. Thus these portionsextend in substantially vertical alinement and are braced at the loweredge of the body section 12 and at the cornice against displacement ofthe body section 12 in the crate, by the same upright members of thecrate, these members being represented at 54, thus avoiding thenecessity of providing separate brace members for these parts.
